A motion moved in the Lok Sabha to express that the House no longer has confidence in the Council of Ministers, which must resign if it is passed.
The 50-member threshold, the link to collective responsibility under Article 75, and the Lok-Sabha-only feature are standard exam facts.
A no-confidence motion (against the whole Council, no reasons needed) differs from a censure motion (can target a single minister, must state reasons) and from a concept confidence motion which the government itself moves to prove its majority.
Lok-Sabha-only motion (50 members) against the whole Council of Ministers; if passed, the government must resign.
